View source for CI750 Computer Interconnect Interface

The '''CI750 Computer Interconnect Interface''' is the [[Computer Interconnect|CI]] interface for the [[CPU/Memory Interconnect]] (CMI) [[bus]] of the [[VAX-11/750]].

It connects to one CI node directly, or to multiple CI nodes using the [[SC008 Star Coupler]].

It consists of:

* The [[CMI]] card L0009 - VAX-11/750 CCI (CMI Cluster Interconnect Module), that is placed into the VAX-11/750 CMI [[backplane]].
* The CIPA (CI Port Adapter) Unit, made of:
** H9542 - 40" Medium System Cabinet Kit, containing:
*** 70-20407 - CIPA Power Supply
*** xx-xxxxx - CIPA Mounting Box ([[DEC part number]] still unknown), containing:
**** 54-15555 - CIPA Backplane, containing:
***** L0100 - ILI (I Link Interface Module), or
***** L0118 - ILI (I Link Interface Module) for up to 32 Nodes
***** L0101 - IPB (I Packet Buffer Module)
***** L0400 - CDP (Data Path Module)

The CI750 uses the same CIPA (CI Port Adapter) as the [[CIBCI]] - [[VAX Bus Interconnect|VAXBI]] CI Interface, 1st generation

The L0009 in the VAX-11/750 and the CIPA are connected using the 70-19602 - L0009 to CIPA Cable.

CI750 revisions are covered in the [[VAX-11/750 & VAX-11/751 Revision Control]] document.
